Abstract

Cette invention concerne un compresseur à mécanisme monté à l'intérieur d'un corps scellé hermétiquement. Un bloc-cylindres renfermant une pluralité de pistons alternatifs est couvert par une culasse. Les chambres de compression comportent une soupape de refoulement qui permet au frigorigène de passer dans un collecteur de refoulement. L'objet de l'invention comporte un mécanisme de limitation de surpression prenant la forme de culasses assemblées au carter par des moyens élastiques et servant à prévenir l'endommagement par surpression, notamment par des coups de bélier. La limitation de surpression peut aussi être assurée par un disque frangible ou une soupape dans le collecteur de refoulement.
